AB  - Radiation hormesis is a biological phenomenon whereby a relatively low doses of radiation
induce beneficial effects on biological parameters, such as viability, growth, and metabolic
profile 1. A number of studies have documented stimulatory effects of low-dose X- and
gamma radiation on plant growth 2. However, radiation hormesis has not been investigated
in microalgae which are becoming a highly relevant source of lipid-derived biofuels. The
aim of this study was to establish the effects of low-dose X-irradiation on biomass and
lipid production in Chlorella sorokiniana. The microalgae cultures were exposed to total
doses of 10, 20 or 50 Gy at different irradiation rates (0.565; 2.290 and 5.057 Gy/min).
Absorbed doses corresponded to ~10% of the total dose, as determined by dosimetry. Lipid
content was determined 30 days after irradiation using Nile Red fluorescence assay with
excitation/emission maxima at 530/570 nm (total lipids), 480/575 nm (neutral lipids) and
549/628 nm (polar lipids) 3,4. Lipid content was normalized to dry biomass.

AB  - Pozitivan biološki odgovor ćelije ili organizma na stres niskog intenziteta se naziva hormezis. U višim biljkama je hormezis kao odgovor na niske doze zračenja dobro dokumentovan ali ovakva ispitivanja do sada nisu rađena na mikroalgama. Mikroalge su grupa organizama koji se lako prilagođavaju nepovoljnim uslovima sredine i na taj način mogu proizvesti veliku biomasu pri niskom sadržaju nutrijenata.Cilj ove studije je bio da ispita odgovor jednoćelijske zelene alge Chlamydomonas reinhardtii (CCAP 11/32C) na niske doze X-zračenja. Ispitivan je efekat na produkciju biomase kao i na promene u zastupljenosti hlorofila a (Chl a) i b (Chl b) u različitim fazama rasta nakon izlaganja tretmanu. Alge su izlagane zračenju od 10; 20; 50 i 100 Gy pri brzinama od 0,565; 2,290 i 5,057 Gy/min. Tretman od 10 Gy je pri brzini od 0,565 Gy/min doveo do povećanja biomase za 21±15% 15 dana nakon tretmana, a pri brzini od 2,290 Gy/min do povećanja od 19±8% već nakon 5 dana. Tretman od 20 Gy je pri brzini od 0,565 Gy /min doveo do povećanja biomase od 22±12% nakon 15 dana. Svi ostali tretmani ili nisu imali efekta ili su doveli do smanjenja biomase. Meren je i efekat zračenja na sadržaj Chl a i Chl b (μg/mg suve mase). Sadržaj ovih pigmenata vremenom opada ali neki tretmani su doveli do smanjenja ovog efekta. Doza od 20 Gy pri brzini od 2,290 Gy/min je dala najbolje efekte na očuvanje Chl a i Chl b i oni su u odnosu na kontrolu bili veći 31±9% i 31±8%.
